Since this year, change jobs, change language, change tools, and don't change it. Delphi, Java, C , samples samples. There are many detours in the learning process. There are also some experience. Just and write them here, let us be sad and happy together. Simply write down this year's experience, you will be slowly expanded later. Before June, the Delphi was developed using the MIS system. After the hopping, make a telecom value-added business. First plan to make a SMS game, Nai Miyu's planning is because of the illness, just give it. Then I did a few SMS products, and it was not very good to promote. By the way, it has been managed in its inatropolis, learned from JSP / Servlet, JavaBean, Hibernate, Struts and other technologies. He has always used Java, developing tools with Eclipse. Recently I have started mobile application development, learn Symbianos, C . Praise. Fortunately, I have entered the door. For Symbianos's structure, the API has some understanding and practice. However, C is really complicated, far more troublesome. The above is probably the experience of this half year. I feel very much, and then continue.
